The subset sum problem (SSP) is a decision problem in computer science. In its most general formulation, there is a multiset $${\displaystyle S}$$ of integers and a target-sum $${\displaystyle T}$$, and the question is to decide whether any subset of the integers sum to precisely $${\displaystyle T}$$. … See more The run-time complexity of SSP depends on two parameters: • n - the number of input integers. If n is a small fixed number, then an exhaustive search for the solution is practical. • L - the precision of the … See more SSP can be solved in pseudo-polynomial time using dynamic programming. Suppose we have the following sequence of elements in an instance: $${\displaystyle x_{1},\ldots ,x_{N}}$$ We define a state as a pair (i, s) of integers. This state … See more • Cormen, Thomas H.; Leiserson, Charles E.; Rivest, Ronald L.; Stein, Clifford (2001) [1990]. "35.5: The subset-sum problem". Introduction to Algorithms (2nd ed.).

Inclusion–exclusion The most naïve algorithm would be to cycle through all subsets of n numbers and, for every one of them, check if the subset sums to the right … See more Suppose all inputs are positive. An approximation algorithm to SSP aims to find a subset of S with a sum of at most T and at least r times the optimal sum, where r is a number … See more • Knapsack problem - a generalization of SSP in which each input item has both a value and a weight.
